Abstract :
It is demonstrated that a stack of carefully designed mirrors can be used in conjunction with a femtosecond dye laser to create high-frequency pulse bursts, pulse codes, and discrete-time signals. The repetition rate was 800 GHz. Once built and assembled the device is easily used. Extensions in the development of this device include longer pulse trains, higher operating frequencies, and variable pulse trains. An important extension in both the theory and the construction of this device is the control of the temporal phase of the pulse train.<>
